Well, if a company comes through, you should publicly thank them. It wasn't easy though. We had to pursue a warranty return. The JVC Support page seems to have an option for submitting a warranty repair request. Alas, there is no option for actually submitting a warranty repair request. To purchase a part; yes. Seems incredibly inefficient and outdated that a major company such as JVC wouldn't have a way to submit a warranty repair request.
There is an online form that you can submit, but JVC never responded. I made several submissions of that form. Eventually, I pressed on and called their Customer Care Center at 800-252-5722. I was expecting the usual automated telephone menus that prevents you from talking to a real live person. After a few fitful instances of number punching, I did reach a live person and that live person took the repair order. I just received my part. Success. Amazing!
